Performance of very special visual tasks of extremely low contrast and small size 10000 – 20000 Specialised

Calculating Illumination

Illumination can be calculated as
I = Ll Cu LLF / Al (1)
I = illumination (lux, lumen/m2)
Ll = lumens per lamp (lumen)
Cu = coefficient of utilization
LLF = light loss factor
Al = area per lamp (m2)

Example – Illumination

10 incandescent lamps of 500 W (10600 lumens per lamp) are used in an area of 50 m2.
With Cu = 0.6 and LLF = 0.8 illumination can be calculated as

1 = 10 (10600 lumens) (0.6) (0.8) / (50 m2)
= 1018 lux
